To all whom z5 may concern Be it known that l, SanctiJ B. fnntnoiv, 4a citizen of the \United States, residing at Dulutln in thecounty of St. Louis and 5.. of Minnesota, have invented certain new and useful Improvements in Gas-Producers, of

-Which the following' is a specification.

This invention relates to gas producers and more particularly to gas producers of thev rotary body type.

- .The object of this invention is to provide a-simple and effective gas producer arrangement` wherein the parts including` the rotary l body, coperate in'a noyel manner to meet the requirements for successful'commercial operatiom the poker 'mechanism being arranged lto operate in a manner to maintain the fuel bed in a uniformly porous con' 2o These and other objects are accomplished by means ofthe the accompanyingsheets of drawings, in which* Figure' l is a fragmentary Vertical transverse sectional 'view of a gas producer enr bodying my invention,

. Fig. 2 is a plan view thereof, and

Fig. 3 is a vdetail view. of the cable suspens'ion means and the manner of connecting the cables to thepokers. Referring to the figures of the drawings, itgwill be noted that have shown a gas )['iiroducer.having a body l() which` in this particular instance isa rotary body. rl`his .body ll is provided with a stationary top i 11 which is provided with a verticallyr extending annular flange l2 extending down intothe annular channel member .l-3 on the top of the body lt), the channel 13 being 40""provided with a sufficient quantity of 'water to'form a seal to prevent lthe escape of gas.

Mounted within the body of the producer gare .pokers letg'which` preferably are arranli'edlin a manner to treat the entire fuel 4a-.bedduring one complete rotation of the body 10.. that is to say, that one ofthe pokers left treatst-he fuel in the outer circular porhtio'n of the fuel bed and the other poker '14 treats the fuelin the inner circular' portion of. the fuel. bed. These -pokers are pro Avided With'shanks l5 each' of which extends through a ball member 16, which, with a :socketi'l mounted on the top ll forms a ball and socket joint whereby the active end of the poker may lag1 when it is within the fuel bed and tht-body l0 is being rotated.

Specification of Letters Patent.

Statev which 4pass over .the

arrangement- 'disclosed by rat-eared 'if-tag.' ai', 192e,

seran No; 260.995.

The opening lS'in the'casting forming part o t the socket 1T is sutiicientlylarge'especiallyiin the lateral liney of movement foftlie poker to permit the active kend oftlie'pokers 14: to lag the necessary amount. Each-poker shank l5 1s provided with' across bar 19 to the ends of which cables 2O are connected pulleys 2l and which terminate in a single cable passing around its associated n turn beingl connected to their correspond ing` sheaves .ln this connection it will be noted-that one of the cables 22 is connected .on one side of its shcave 24 and the other cable 22 is connected on the other side of its sheave. These sheavesV are mounted upon a shaft 25 which is oscillated back and forth by any suitable mechanism, such. for instance` as the crank arrangement 26, here shown. By means of the connection between the sheaves 2t and the poker shanks l5` it is apparent that as one of the pokers is positively raised, the other is permitted to lower by gravity as a result of its own weight. The particular advantage in having' the pokers lower by gravity instead of being positivelythrust into the fuel bed is that vthe pokers are permitted to sink into the fuel bed in accordance with. the condition thereof. The pokers will sink into the fuel bed a vcertain predetermined amount unless otherwise stopped by the resist-ance ofthe fuel forming the fuel bed. It is clear that if the fuel bed is relatively free of chunks of coal the pokers will sink into the fuel bed substantially. the same amount througl'iout the entire bed. lf, on the other hand. in lowering. the pokers encountered a relatively large chunk of coal the resistance to 'the downward poker movement is increased.l

and in this connection it is to be noted 4that if the pokers were positively driven an undue packing: of the fuel bed would result. llowever. `with Athe arrangement herein dis closed the pokers sink into the fuel bed by their own weight and in a manner to maintain the fuel bed in a uniformly porous condition. As the body rotates. it is apparent that the working ends of thepokers will laga certain amountwhen said ends of the pokers are sunk into the fuel bed, thereby causing the fuel bed increment by increment to be disturbed slightly inthe lateral direction which is to-advantage in manufacturing` ,ga-s.

Itis my intention to cover all modificapulley 23, the cables in tions falling Within the spirit and scope of Y the following claim.

I claim l In a 'gas producer, the combinationof a rotary body, a stationary top therefor sealed y with respect to the body to prevent the l v l o f relatively large poker receiving opening's therein, a plurality oli-'vertically movable escape of gas, saidtop having a plurality poke'rs extending loosely through said top Vopenings to permit the pokers, when in the fuel, to lag as the body rotates, closures for said openings-including ball'and socket -day of Oct., 1918.

joints to permit the pokersv'to lag, the pokery s Shanks bein?y regularly verticaly and reciprocal'ly movable through the balls re` raised positively and lowered' solelyby` gravity at regular intervals to .maintain the fuel bed in a uniformlyl porous condition.
